I think it is very rare to do this kind of method for normal residential home because it costs a lot of money (hiring the experts) the benefit simply does not cover the cost.

Density (unit count) is generally displayed on a per square foot or per acre ratio.

Just normal conversation with my landlord.

@Lexi TeifkeHi Lexi, is it difficult for a agent to obtain the comps info and is it normally a fee?

The return for a flip, especially if you've overcome the lead paint issue, would put you in another bracket as well.As for the existing 2 bedroom,  I'd try to switch the living room with that one bedroom upstairs unless it's normal in that area to have living rooms downstairs.

Plan to build up my Portfolio with the BRRRR Method as well.When you purchase a house with a HELOC make sure you also add the minimum payment for the loan to your expenses (lot of people forget to add this and wonder where there cashflow is) but when you Buy, Rehab, Rent, then get to the Refinance part the bank will normally give you 65 to 75 percent of the ARV, and the appraiser will base it on the current comps in your market.Check out this article from @Andrew Syrios    https://www.biggerpockets.com/renewsblog/brrrr-buy...

I turn down 3-4 homes per month that I would normally buy because I dont have the funds.  

This is largely because I live for free, bike or make a short drive to work (I injured my foot and haven't been able to bike as much recently), and bring lunch to work. 

The hot water heater provided both the normal hot water, plus had another loop that went up to the HVAC exchanger to provide heat in the winter.

Is that normal?
